A local machine shop added LT-4 2.00" intake and 1.55" exhaust valves with a 3 angle valve job and LT-4 springs. I added a GM LT-4 "Hot" cam and 1.6:1 roller rockers with Cloyes timing set. The intake is a Chinese "Crosswind" copy of a RPM Air Gap, if I did it again I would have spent the extra money and purchased an Edelbrock, the offshore quality is poor. That said, I attacked the intake with a Sawzall and grinder and removed the extra lumps, bumps, weird mountings and "nitrous nozzle" bosses. I added a PCV valve (with baffle) in the valley so that I could use the Moon breathers without oiling the engine compartment. I then sent it to LO-KO Coatings for a ceramic coating, they do outstanding work. The valve covers are Ebay finned no hole centerbolt, with Moon breathers added, the carb ia a Holley 770 cfm Street Avenger with a Moon oval air cleaner. The engine is green same as the truck is going to be, I couldn't beleive that you can get dark green engine paint. Here are a couple of pictures, I hope to post more of the truck as work continues.
